To all whom it may concern:

view in front elevation of the upper portion Be it known that I, EDWARDPoHL, a citiof one element of the machine, including the zen of theUnited States of America, and a means for applying the finishing andlusterresident of New York, county and State of ing solution to aplurality of filaments to New York, have invented certain new and usefulImprovements in Silk-Thread-Finishing Machines, of which the followingis a specification, reference being had to the accomp anying drawings,forming a part thereof.

My invention relates to sill; thread finishing machines and particularlyto the type of machine in which a finishing or lustering solution isfirst applied to the threads, and the threads thereafter ironed andpolished by being drawn over a heated. contact surface.

My present invention consists in means whereby a plurality of threadsmay be assembled in close parallel relation either after or before afinishing and lustcring solution has been applied thereto, whereby thethreads will be grouped together as a single thread comprising aplurality of filaments, the threads being ironed and polished in thiscondition and finally taken up upon spools as single threads. A threadcomprising several filaments as so described will differ essentiallyfrom the usual form of spun thread having several filaments, in that inthe latter form of thread, the filaments are twisted into substantiallyrope form, while in the former, the threads lie side by side in parallelstraight lines.

My invention also consists in certain details ofconstruction andcombinations ofparts including a means whereby the breaking of a singlefilament will stop the take up means for the thread of which thatfilament forms a component part, and a novel form of movable guide forforcing the threads to pass through the bath containing the finishingand lustering solution.

In order that my invention may be fully understood 1 will now proceed todescribe an embodiment thereof, having reference to the accompanyingdrawings illustrating the same, and will then point out the novelfeatures in claims.

In the drawings: Figure 1 is a view in transverse section of a machineembodying my invention. Fig. 2 is an enlarged detail form a singlethread, the take up means for the thread, and the stop motion, theheated contact member being removed. Fig. 3 is a detail view of certainparts of the stop motion showing the same in their tripped position.Fig. 1 is a top view of the same and showing also part of the means forapplying the finishing and lustering solution to the threads. Fig. 5 isa detail view in transverse section of parts of the winding or take upmeans showing also the stop lever therefor.

v The machine comprises generally a group of supports 10 for thefilaments or threads to be treated, means 11 for applying a finishingand lustering solution to a group of filaments to form a single thread,a heated contact member 12 for the thread and winding or take up means13 for the thread after it has been ironed and polished. The particularmachine shown is designed for treating a number of groups of threads orfilaments to form a number of individual threads, each individual threadto be formed having its own solution applying means, its own heatedcontact member, and an individual winding device. As various groups ofparts are similar throughout, 1 will describe a single set of such partsjust as if the machine were de signed for producing but a single thread,it being understood that the same explanation would serve for the largenumber of similar groups of mechanism which I ordinarily employ in onemachine. I

The filaments to be treated are mounted in the machine on four bobbins14. located upon spindles 15 which are supported by a'central plate 16formed as a part of the frame of the machine. The said filamentspassthrough individual guiding elements 17 and thence beneath a guide rod 18located in the bath 19 which forms a part of the solution applying means11. The guides 17 are formed in the end of a plurality of levers 20which are loosely strung upon a shaft 21, the said levers 20 beingsupported wholly by the filaments whereby they are free to drop in caseany filament breaks. The filaments in passing under the guide rod 18 arecompelled to pass through the solution contained in the bath. 19

wherein they each pick up a modicum of the solution, and thereafter theypass through a common guide 22 wherein they are caused to run togetherto form a single thread. This thread then passes over or through a brush23 by means of which the surplus moisture is removed, thence over aguide roller 24, thence downward along one face of the heated contactmember 12, thence under and around a guide roller 25, thence upward.along the opposite faces of the heated contact member 12, thence over aguide roller 26 at the upper end of the heated contact member 12, thenceover a traversing guide 27 and thence around a take up spool 28. Thetake up spool is provided with the usual pulley or whirl 29 which isarranged in contact with a drive pulley 30 and by which the bobbin isfrictionally rotated to take up the thread. This taking up of the threadupon the bobbin 28 is what causes the feed of the thread throughout theentire machine, the individ ual filaments being drawn from their bobbins14 thereby, carried through the bath, formed into a single thread, andthen drawn over the heated contact member so as to receive the ironingand polishing.

In order that the take up may be stopped should any one of theindividual filaments break, I provide a stop means common to all of thefilaments of any one group which operates upon the take up bobbin toprevent its further movement i-vhenever the stop motion be tripped. Thisstop motion com prises a lever 31 which extends beneath all four of thelevers 2 0 which carry the guides 17 for the individual filaments, thesaid lever 31 being normally just overbalanced by means of acounter-balancing weight The said. lever is provided with a catch 33which normally engages the end of an arm as is shown in Fig. 2, the saidarm 34L being con nected by means of a link 35 with a stop lever 36. Thesaid stop lever 36 has a tooth 37 at the end thereof which, when thesaid lever is dropped, is adapted to engage with the teeth 38 of aratchet wheel which is secured to rotate with the bobbin 28. Normallythe stop lever is held in such a position that its tooth will be clearedof the teeth of the ratchet wheel as is shown in Figs. 2 and 5, butshould any one of the levers 20 fall, consequently upon the breaking ofthe filaments which it guides, it will so fall upon the lever 31, andthe weight thereof, resting upon. the lever 31., will rock the saidlever upon its pivotal support so as to release the catch 33 fromengagement with the arm 34. The arm 34, link 35, and stop lever 37 willnow be free to drop, and in so dropping the said stop lever will engagethe ratchet wheel 38 whereby to hold the spool or bobbin 28 againstfurther rotation. To re-set the stop motion, it is only necessary tolift the guide lever 20 and then to again cause the arm 341 to beengaged by the catch 33. By the foregoing means, it will be seen that ifany one of the individual filaments for any threads break, the take upmeans for that particular thread will be stopped, but that the stopmotion will in no way affect any other part of the machine, so that therest of the machine will be free to continue to operate as before.

In order to facilitate the threading up of the machine when firststarting, and to permit the threads to be readily moved out of thesolution contained in the bath 19 if the machine be stopped for anycause, I have mounted the guide 18 so that it may readily be moved intoand out of the solution contained in. the said bath. The guide 18 is sup)orted by carrier arms 39 which are piv-' ota y mounted at 40 inbearings upon opposite sides of the said bath 19. A manual operatingmember 41 is secured to the car rier whereby it may be readily operatedby hand, and a stop 12 also connected with the said carrier limits themovement of the carrier in one direction, 11. e. in the direction oftravel of the thread. By this means, the.

travel of thread itself tends to keep the guide in its position in thebath, but if for any reason it is desired to remove the guide from thebath, it is only necessary to swing the hand lever in the oppositedirection as will be well understood by reference to Fig. 1 of thedrawings.

What I claim is:

1. In a silk thread finishing machine, the combination with means forapplying a finishing and lustering solution to a plurality of filaments,of means for assembling the filaments in close parallel relation to forma single thread, and means for drying, ironing and polishing the threadcomprising the several filaments substantially as set forth.

2. In a silk thread finishing machine, the combination with means forapplying a fin ishing and lustering solution to a plurality ofindividual. filaments, of means for assembling the filaments in closeparallel relation to form a single thread, means for drying, ir0n' ingand polishing the thread, a take up means for the thread, and meansoperated by the breaking of any one of the individual filamen ts forstopping the take up means.

3. In a silk thread finishing machine, the combination with means forapplyinga finishing and lustering solution to a plurality of individualsilk filaments, means for assembling the filaments into close parallelrelation to form a single thread, means for ironing and polishing thethread so formed, a take up means for the thread comprising a bobbin andfrictional means for rotating the same, a plurality of guiding leverssupported by the individual filaments, a stop lever adapted to engagethe bobbin to stop the same from further rotation, a catch for normallyholding the stop lever out of engagement with the bobbin, and trippingmeans common to each of the several guide levers for causing the catchto release the stop lever.
